Twitter Sharing Not Displaying

Our technical theme team are aware of this issue and have a fix in the pipeline. We are checking and fixing to update it and release it as soon as possible, maybe, it’s in the today, so for now disabling the twitter badge is the best option.
Twitter are ending support for retrieving share counts, which is the underlying cause of this error. They said they’d remove their special share count URLs in October, but it looks like they’ve taken the API endpoints down a little early!

The next version of the theme will resolve this issue; twitter badges will no longer display counts, but will otherwise function as normal.
Sorry for the inconvenience with this, and I hope that helps to clarify things.
Regards,
